Is There Anything I Can Do?

[IanD]

Afternoon folks,

Unless i'm not thinking things through correctly, i'm in a bit a quandary for this afternoon after work.

So, i'm off to a place with a lake/pond to try and get a few sunset pics.

I want/maybe need to use my ND filter to get the shot i'm after, which is fine, screwed on to my 16-35mm 82mm fitting lens.

But, the only polarising filter I have is 77mm.

I have a step-up ring but once I screw that on to my 77mm polarising filter, then screw in the 82mm ND filter, it's going to turn the polarising filter which I would already have set to take the glare from the water.

Is there anything short term I can do, and long term also?

Will I really need a polarising filter as the sun sets?

Will the ND filter help in any way?

Thanks all

If your polariser still has the little handle screwed into it, use that to keep the pol set how you want it while you screw in the ND and step up/down ring. Don't forget that using a smaller filter than that which the lens is designed to take (eg 77mm filter on 82mm filter thread) will almost certainly introduce a vignette.

Thanks for the quick reply. Wasn't aware of the vignetting issue. Maybe for long term I'll get an 82mm polarised too.

Not sure what you mean about a handle on it though. It just screws on to the lens and I turn the ring to adjust

Could you put a small mark across the join on the filter and lens where it needs to match up so you can re align it?

That's a good idea @keef32

I could try that

All my pols have a little handle that screws into the side of the mobile bit of the pol. IIRC, Hoya pols have a white line on them for situations like yours.
